STOCKHOLM, Aug. 30 (Xinhua) -- Meat diet, a dietary habit popular in some developed countries, can produce more greenhouse gas and thus is likely to actually cause more impact on climate, said a Swedish study published Tuesday.According to Swedish Radio's Ekot news program, the meat diet, also known as Low Carb High Fat (LCHF) diet, doubled the greenhouse gas emission compared with the balanced diet recommended by the Swedish Food Administration.Many Swedish people have abandoned the diet habit of eating root vegetables and fruits, and switched to LCHF diets. The LCHF diet has more meat, fat and unusual greenhouse gas emission. But these root vegetables, such as potatoes and carrots, and other naturally grown vegetables can be planted with less greenhouse gas emission.The report also revealed that many of the LCHF diet advices are actually given by the researchers sponsored by meat industry.

SINGAPORE, July 3 (Xinhua) -- The over 60 nursing homes in Singapore, especially those run by voluntary welfare organizations, are facing a bed crunch, local daily Straits Times reported on Sunday.The newspaper found in a check with 20 homes that more than half of the nursing homes were running at full or almost full capacity. Homes run by voluntary welfare organizations, where there are subsidized beds, have long waiting lists.The average waiting time for a bed in nursing homes run by voluntary welfare organizations rose from 50 days in 2008 to about 60 days early last year, the newspaper said.It is easier to get a bed in a privately run home, though only slightly and if you can afford it. Econ Healthcare Group, which runs eight nursing homes in Singapore, said the occupancy rate is 99 percent and it has waiting lists of up to 20 people at some branches.Demand for nursing homes in the city state can only grow given the aging population. By 2030, the number of people aged 65 or above is projected to reach 900,000, or one in every five residents.

LOS ANGELES, June 17 (Xinhua) -- The size of low-oxygen zones created by respiring bacteria is extremely sensitive to changes in depth caused by oscillations in climate, thus posing a distant threat to marine life, a new study suggests."The growth of low-oxygen regions is cause for concern because of the detrimental effects on marine populations -- entire ecosystems can die off when marine life cannot escape the low- oxygen water," said lead researcher Curtis Deutsch, assistant professor of atmospheric and oceanic sciences at University of California, Los Angeles."There are widespread areas of the ocean where marine life has had to flee or develop very peculiar adaptations to survive in low- oxygen conditions," Deutsch said in the study to be published in an upcoming print edition of the journal Science.A team led byDeutsch used a specialized computer simulation to demonstrate for the first time that fluctuations in climate can drastically affect the habitability of marine ecosystems.The study also showed that in addition to consuming oxygen, marine bacteria are causing the depletion of nitrogen, an essential nutrient necessary for the survival of most types of algae."We found there is a mechanism that connects climate and its effect on oxygen to the removal of nitrogen from the ocean," Deutsch said. "Our climate acts to change the total amount of nutrients in the ocean over the timescale of decades."Low-oxygen zones are created by bacteria living in the deeper layers of the ocean that consume oxygen by feeding on dead algae that settle from the surface. Just as mountain climbers might feel adverse effects at high altitudes from a lack of air, marine animals that require oxygen to breathe find it difficult or impossible to live in these oxygen-depleted environments, Deutsch said.Sea surface temperatures vary over the course of decades through a climate pattern called the Pacific Decadal Oscillation, during which small changes in depth occur for existing low-oxygen regions, Deutsch said. Low-oxygen regions that rise to warmer, shallower waters expand as bacteria become more active; regions that sink to colder, deeper waters shrink as the bacteria become more sluggish, as if placed in a refrigerator."We have shown for the first time that these low-oxygen regions are intrinsically very sensitive to small changes in climate," Deutsch said in remarks published Friday by the American Association for the Advancement of Science on its website. "That is what makes the growth and shrinkage of these low-oxygen regions so dramatic."Molecular oxygen from the atmosphere dissolves in sea water at the surface and is transported to deeper levels by ocean circulation currents, where it is consumed by bacteria, Deutsch said."The oxygen consumed by bacteria within the deeper layers of the ocean is replaced by water circulating through the ocean," he said. "The water is constantly stirring itself up, allowing the deeper parts to occasionally take a breath from the atmosphere."A lack of oxygen is not the only thing fish and other marine life must contend with, according to Deutsch. When oxygen is very low, the bacteria will begin to consume nitrogen, one of the most important nutrients that sustain marine life."Almost all algae, the very base of the food chain, use nitrogen to stay alive," Deutsch said. "As these low-oxygen regions expand and contract, the amount of nutrients available to keep the algae alive at the surface of the ocean goes up and down. "Understanding the causes of oxygen and nitrogen depletion in the ocean is important for determining the effect on fisheries and fish populations, he said.

BEIJING, June 28 (Xinhuanet) -- A truck-sized asteroid passed over the Atlantic Ocean within 7,500 miles of the Earth on Monday, according to NASA's Jet Propulsion Laboratory.The space rock, called asteroid 2011 MD, is the second space rock to zip extremely close to the Earth this year.The asteroid, with latest size estimates ranging from 16 to 66 feet (5 to 20 meters) wide, was discovered just last week on June 22, but there was never any risk of it impacting the Earth, NASA scientists said. That means asteroid 2011 MD would likely be too small to survive the fiery plunge through the Earth's atmosphere, let alone reach the surface, NASA scientists said. Asteroids this size can be expected to buzz Earth with close shaves about once every six years, they added.The space rock flew well below geosynchronous satellites, which orbit 22,236 miles (35,786 km) above the Earth, but well above the 220-mile (354-km) altitude of the International Space Station.There was little chance that the asteroid would hit a satellite because of the vastness of space and relatively small number of satellites, experts said.

VANCOUVER, Sept. 18 (Xinhua) -- At the fourth International Qigong Tournament and Exchange currently going on in Vancouver, many of the competitors spoke Sunday of how the practice had improved their lives after being able to overcome the complications of illness and injury.While many of the more than 300 competitors in the eight-day tournament were out to demonstrate they were among the best practitioners in the world, others were clearly happy to be competing after previously living with various ailments that had affected their mobility and overall way of life."I've been very ill," said competitor Felicia Kazmer of the New Jersey-based U.S. Health Qigong Association. "I have Lyme disease and infections. I was out on medical for six months last year and through the practice of Qigong, and especially the intense practice because I knew we were coming to the tournament, I am feeling better than I have in years and years. I know that this has opened the meridians and allowed the qi to flow and it's worked better than any drug."While Qigong has been practiced in China for centuries, it is relatively new to the outside world. It is for this reason that after holding the biennial International Qigong Tournament and Exchange in China on the first three occasions, the event was moved abroad for the first time to help increase its awareness and growing popularity.Altogether, 44 Health Qigong teams are in Canada from 25 nations and regions for the tournament.Philip Moot, a 26-year-old from The Hague, was attending the tournament for a second time after taking in the last competition in Shanghai in 2009. Now studying Chinese acupuncture, the Dutchman said he took up Qigong after suffering from Pfieffer, a glandular fever that is a fatigue illness."I was always tired and when I woke up in the morning I felt already tired. Then I started with Qigong and exercises and it improved my health enormously. I'm doing it now, I think four years, and it made me stronger. The tiredness is gone."Moot said the more you put into Qigong, a series of movements and postures that focuses on regulated breathing techniques, focused meditation and self-massage, the more a person will get out of it.He compared the practice to charging up a battery and added he had now turned his parents on to Qigong, as well as a friend's father who is battling cancer. "It's helping him also to relieve the pain a little and not to think constantly of this disease."According to various clinical studies, the regular practice of Qigong has shown to be beneficial in reducing stress, better balance, lowering blood pressure, enhancing the immune system, improving sleep patterns, as well as improved cardiovascular, respiratory, circulatory and digestive functions, among many others.Depending on who you talk to, the benefits of Health Qigong means different things to different people, according to practitioner Susan Gallin. The New Jersey nurse took up the practice 18 months ago after undergoing knee surgery."But after the surgery my knee was never back to normal. So someone suggested to take Qigong," she said. "And I started taking it and it was amazing. I guess maybe after a couple of months my knee started to feel better and I'm not 100 per cent right now, but I do really well. I can squat down, things I couldn't do before the surgery."Working in the medical industry, Gallin said she was at odds with the western mentality of taking pills for everything. She felt hospitals should offer more wellness programs than they do."Some of the hospitals in the United States offer such things that include this type of alternative medicine, but I don't think it's enough. Some of the bigger pharmaceutical companies offer wellness programs before the hospitals and you would think we are in a healthcare system that they would offer a wellness (program), try to keep you well so you don't get sick. I know for myself I always try to do whatever I can before I take a pill."Reg Carter knows what it is like to endure a steady diet of pills after having to take anti-inflammatories and painkillers for problems with his joints. For the past two years the native Derby, England, has been practicing Qigong and was in Vancouver as part of the British team taking part."I had shoulder injuries, a broken collarbone, arthritis of several joints, elbows, my hands, fingers and the mobility has improved considerably since I've been doing the Qigong. The mobility has improved and also with the strengthening through the lower body and legs. The back injuries has improved. I don't get so much pain and I find I can move about a lot more fluidly," he said."I just feel like I've had a lot more life balance. I feel a lot more calmer. My sleep pattern's improved. I don't get angry so often, and if I do I find that I can get to grips with it and keep a lot calmer."Toronto resident Karen Widmer has never endured the pain suffered by Carter, but credits the energy of Qigong in aiding the recovery of a broken wrist she suffered four years ago while studying a level one Qigong course.Through regular practice, Qigong practitioners are said to be able to direct the energy in the body, the qi, towards the limbs."I completed it (the course) with a broken wrist and I could feel the energy repair much faster and the recovery time was better than they had actually thought," said the yoga instructor.Now totally hooked on Health Qigong and with 5,000 hours of practice to her credit, the 50-something Widmer explains it takes 10,000 hours of practice to achieve the title of "master.""While it looks like a physical process, it's actually very much more a spiritual process. Since we are electro-magnetic beings, it makes sense that we could send that current around in a positive way. But it does lead a person to longevity. It's a wellness that is authentic and I hope to be 100 years old and still doing it," she said."I have always enjoyed movement knowing that movement is health. And I would say that even people who aren't athletic can do this. It helps balance. Balance prevents falls, which prevents breakage. It is very beneficial to do this."
